防止堆石坝面板混凝土裂缝的措施之一是提高混凝土的抗裂性。通过配合比优化，为天生桥一级水电站钢筋混凝土面板设计出抗裂性能较好的混凝土。研究提出了一个衡量混凝土本身抗裂性的指标——混凝土抗裂性指数
One of the measures to prevent the concrete of the rockfill dam from cracking is to improve the crack resistance of the concrete. Through the optimization of mixture ratio, the concrete with better cracking resistance was designed for the reinforced concrete slab of Tianshengqiao I Hydropower Station. The study proposed a measure of concrete crack resistance index - concrete crack resistance index
